I purposely made that the lowest spot, so water would go to there and not any farther. It's not in the pic but i drilled a hole just to the left of the end of the clamp and i guess i made it too big, because when i powerbrake or blow smoke sitting still you can see a little cloud come out from under the truck

Keep in mind, that the pipe itself has to flex, because the downpipe is connected to the engine, and i believe the pipe flexes to absorb engine movement. This is why i want a bellows in the system right behind the downpipe, to isolate as much exhaust pipe from the engine as possible. Thats what causes drone.
